Titre | Random Field Ising Model and Parisi-Sourlas Supersymmetry |
Résumé | We will discuss the phase transition in the Ising model with magnetic impurities. By one kind of lore, this leads to a non-unitary supersymmetric CFT with scalar supercharges (Parisi-Sourlas supersymmetry). By further lore, Parisi- Sourlas SCFT in D dimensions is equivalent to a non-SUSY CFT in D-2 dimensions. It is known that this story is not fully correct, but we will put at least some of it on firmer ground using non-perturbative CFT methods. Joint work with Apratim Kaviraj and Emilio Trevisani. |
